Keller is a print addict, so he's doing this to "better
understand the joys and frustrations of our journalism delivered
online." Here's what he's figured out so far:

Of the various platforms, I find NYTimes.com on a desktop the most
satisfying, but, obviously, the least portable. TimesReader comes
closest to the pleasure of a printed paper, but a notebook is not
ideal: great for a plane ride, not so great for a subway ride.
I like the Kindle fine for books, but for a newspaper it
seems a bit balky and drab. Love the iPhone app but,
like AP, BBC and all the other news apps that scroll through a
list of headlines, it inevitably feels linear. I find myself
wondering whether anyone — even the geniuses at Apple — can come
up with a single device that combines the advantages and
conveniences of these various platforms. Or that makes me quite
as happy as curling up with the Sunday paper spread around me.
